Abstract :This study was conducted to determine the effects of different levels insert ignore into journalissuearticles values(0, 200, 400, 600 mg/kg); of ashwagandha insert ignore into journalissuearticles values(Withania somnifera); root powder insert ignore into journalissuearticles values(ARP); on performance, egg quality and egg lipid peroxidation in laying hens insert ignore into journalissuearticles values(Lohmann LSL, 36 weeks old); diets. For this purpose, a total of 4 groups were formed, one of which was control insert ignore into journalissuearticles values(ARP-0); and the other three were experimental groups insert ignore into journalissuearticles values(ARP-1, ARP-2, ARP-3);. A total of 96 hens were distributed to 4-storey cages with 8 replicates in each group and 3 hens in each replicate. The experiment lasted for a total of 2 months. During this period, feed and water were given as ad-libitum and 16 hours of light and 8 hours of dark photoperiod was applied daily. The ARP-0 group was fed with basal diet and the experimental groups were fed with diets prepared by adding 200, 400 and 600 mg/kg levels of ARP to the basal diet, respectively. Except for egg weight, albumen index, Haugh unit, shell weight, yolk L* and b* and TBARs insert ignore into journalissuearticles values(day 0);, other parameters were not affected by ARP in the diet. The highest egg weight insert ignore into journalissuearticles values(p<0.05); was in the ARP-2 group while the highest albumen index insert ignore into journalissuearticles values(p<0.05);, Haugh unit insert ignore into journalissuearticles values(p<0.05); and shell weight insert ignore into journalissuearticles values(p<0.05); were in the ARP-1 group. It was determined that egg yolk L* insert ignore into journalissuearticles values(p<0.001); and b* insert ignore into journalissuearticles values(p<0.001); values were highest in ARP-1 and ARP-3 groups. Moreover, it was observed that all levels of ARP in the diet decreased the yolk TBARs insert ignore into journalissuearticles values(day 0); value compared to the control group insert ignore into journalissuearticles values(p<0.05);. As a result, it can be said that ARP can improve some quality parameters and delay lipid oxidation in laying hens without adversely affecting performance.
